Thanks for your feedback!

Question 6. a) What is the class range of colony numbers on nutrient agar plates, fewest to most? b) Put the class NA plates into two categories based on their numbers of colonies. c) Calculate a class average number of colonies per plate in each category. Leave out any numbers the class has determined to be unreliable. d) Once you are told the dilution number of each category, calculate the concentration of the ORIGINAL bacterial suspension (cells/ml) from c). Show your calculations. You will have two answers (one from each category). use table below for the values needed (group 1-5 had dilution of 6 while groups 6-10 had dilution of 7)
